Technical writing is a sort of structured writing used mostly by software development companies and engineering firms like Bombardier. The formalities were mostly formalized around highly technical instructions sets like those having to do with aviation. Today, most top software companies, around Montreal, including video game company Ubisoft, live event multimedia company Moment Factory, Game Engine companies like Unity and Epic, all rely on technical writers to counterbalance the narrow view that software engineers must take as applications are developped. Outputs that technical writers create include user guides, for example as PDFs and ebooks, online helps systems (what you get when clicking Help), tutotorial videos like those seen on Youtube for myriad products, etc etc.
